Control with nucleopolyhedroviruses of the fall armyworm and corn earworm on a Bt-transgenic line of sweet corn with limited resistance to the former pest and high levels of resistance to the latter pest was evaluated. The virus of the fall armyworm significantly improved control of this insect on both transgenic and nontransgenic corn. The virus of the corn earworm increased control of its host on nontransgenic corn but provided little additional control on transgenic corn.

Species 1: Lepidoptera Noctuidae Spodoptera frugiperda (Fall armyworm)
Species 2: Lepidoptera Noctuidae Helicoverpa zea (Corn earworm)
Keywords: Microbial control, Virus
